Optimization of lipid extraction from aquatic plant Salvinia molesta D. S. Mitchell (Salviniaceae) with alternative solvents

Salvinia molesta D. S. Mitchell (Salviniaceae) is an invasive aquatic plant that causes environmental and economic damage, but its rapid growth in eutrophic media can be used for the biotechnological use of biomass. Thus, aim this work was to determine best technique lipid extraction from molesta, testing solvents hexane:methanol (2:1 v/v), ethanol:water (10% v/v) (4 % association with auxiliary techniques: ultrasound without glass beads magnetic preparation at 17 34 ºC. The yields obtained were ones 2:1 aid (8.30 ± 0.05%). mixture 10% agitation ºC also potential, as it uses less toxic presents a yield 6.90 0.21%. &nbsp
